I am rebuilding my front axle on my model a and making a parts list of what i need. my king pins are tight and don't seem to have any play but I am able to move my spindle up and down on axle and was wondering how much is ok? I would geuss i have about the thickness of a quarter when i pry it up. And on a side note I know to use the spring compressors but is there one that will do both or have to buy the front and the rear Thanks
